If you still have this, I'll take it.
You have Paypal?
Curious, what's the purpose of optional horn lead tap?
Still have it, PayPal is fine. The horn tap is an optional connection. You attach tot he horn lead and when you hit your horn it will force the modulator to flash 3-4 times whether it is on or not, even at night. Just a little visual attention getter to go along with the horn.
Check your PM for paypal info.
